The present improvements relate, in general to packing for fragile articles and more particularly to packing for radio tubes, incandescent bulbs and the like, although the improvements may be embodied in various other forms adapted for packing and ping individual glassor ceramic'articles.

' primary object of the improvements is to provide a novel one-piece packing for individual fragile articles.

is to provide a novel packing sheet from which a plurality of packing strips may be readily sheared.

A still further object is to providean improved one-piece holder for an individual fragile article which may be easily folded and inserted in an enclosing container.

Another object of the present improvements is to provide a novel collapsible con.-

tainer. having integral cushion means, whereby an article may be packed therein without employing separate or auxiliary packing such as paper, excelsior and the like. .To improve packing means in general, ebtain greaterefliciency therefrom as well as to, reduce breakage of packed articles constitute further objects of the improvements. p 1

Other objects and advantages of the presao ent improvements will be apparent to those skilled in the art upon reference to the accompanying specification and drawings, in-

which v Fig. 1 is a plan view of a sheet of material 36 embodying t e present improvements;

In practicing the present improvements, the packing is -formedof cardboard, wood pulp or other similarmaterial. Preferably the pulp sucking process is employed wherein a collapsible illustrating a the sheet or strips and the projecting porship- A further object .ervation of that form in use,

In forming the sheet and parts thereof, wood pulp, cellulose or other fibrous material is employed, the fibres being first placed in a liquid bath.

The formation of the sheets may then be accomplished by molding or feltin by means of suitable dies or molds wherefiy a sheet of relatively yieldable material results, with the hereinafter mentioned. protuberances therein, all consisting of intimately matted fibres.

These sheets and cushions therein are of such form and are so constructed and arrang- 'ed as to be relatively-rigid, and yet have a sufficient degree of elasticity to accommodate themselves to pressure exerted thereon.

Moreover the nature of the construction insures proper and accurate form and the pres since any pressure on the sheet or any part thereof will tend to move its matted fibres from their normal position into a more intimate union and will be constantly resisted thereby, to the end that the parts will always have a tendency-to return to their original form, which causes them to exert acounter pressure when slightly pressed or drawn therefrom. An inherent resilience and elasticity is thus present in the sheets and parts thus formed, resulting in a cushioning effect under the influence of pressure.

Referring to the drawings, the sheet 10, formed in the foregoing manner, is provided with rows of protruding members 11 and '12 thereon; As illustrated in Fig. 1, themembers 11 form a row adjacent .one edge of the sheet, while members 12 form a row adjacent as 14 are disposed longitudinally of the sheet 10 and serve to divide the sheet into three portions 15, 16 and l7,.two of'which have the aforementioned vpro'tuberances and the g third intermediate thereof, which serves as we a connecting body for the contiguous end portions.

A score line 18 is provided between the protruding members and extends across the sheet 5 thus dividing it into a plurality of strip sections 20, each of whichhas an end portion 15*, an intermediate portion 16* and another end portion 17. Accordingly the sheet 10 may be torn or out into a plurality of strips 20, such as illustrated in Fig. 2.

. Referring more particularly to Fig. 2, the member 12 is dome or cupped shaped and extends beneath the plane of the strip while the member 11 extends above the plane ofthe strip 20 in a direction opposite to that of the protruding member 12. Member 11 is likewise dome or cupped shaped and comprises a frusto-conical wall 11, the upper rim of which merges with a concave dome whose apex approaches the plane of member 17.

When used aspacking for a fragile article,

the flaps 15 and 17 are folded in the same ed over the top thereof and the dome-shaped member 11 grips and surrounds the domeshaped end of the tube. The member 11 likewise serves as a seat for the tube since the tube is firmly supported at both ends regardless of which end of the carton may happen to be down.

As aforementioned, the entirestrips 20 wlth the protruding members thereon. are

. made in one manufacturing operation so that an integral strip results. This strip is rela;

tively rigid but at the same time possesses inherent elasticity and resiliency whereby an article packed therewith is cushioned and protected against shocks from all directions. The intimatelymatted fibres which make up the texture of the strip, constantly'tend to retain their normal relation and any shock or pressure on the strip 1s constantly resisted.

This tendency of the fibres to preserve the form of the strips and parts, promotes eflicient cushioning and protection for the packed article.

' nested-in similar members of sheets above Formation of the strips in s set form, as illustrated in Fig. 1, facilitate manufacture and at the same time is economical. Furthermore, handling and shipping the strips in this form is greatly facilitated sincethe sheets may be. stacked, one upon the other,

with the dome-shaped members of a sheet and below them. A substantial number of these sheets, thus occupy a relatively small space, and maybe shi ped to the fragile article manufacturers or cutting into strips I and use in stock cartons which they may have or; purchase. The strips 20 need not however, be'made in sheet form but may be manufactured individually and independently of one another.

Referring to Fig. 4 a collapsible carton 25 is illustrated in unfolded condition. This carton islikewise manufactured in one operation b the pulp sucking rocess and comprises a ody portion div1 ed by fold lines into wall portions 26. Formed integral with this body portion are a plurality of flaps extending from opposite edges thereof. Flaps.

27 and 28 are formed with dome-shaped members 11 and 12 thereon, while flaps 29 to 32 constitute the usual end portions of the carton which are adapted to be'folded over and tucked in.

The folded carton is illustrated in Fig. 5, wherein the portions 26 comprise the walls of the carton. Flap 28 is folded in to form the bottom ofthe carton, after which flap 30 is folded over and subsequently flap: 29, which latter has a lip for'tucking in. ikewise flap 27 is folded over to form the top of the carton, with flaps 31 and 32 folded over same, in the same fashion as described.

With the article placed in the carton, it is seen that the dome-shaped members provide a seat at each end, in which the ends of the article rest, while the remaining flaps form an enclosing member for the flaps 27 and 28. Accordingly, the article is held against wabbling orsha 'ng relative to the carton. relatively ri 'd carton is thus formed, which ossesses i erent resiliency and elasticity 1n all parts thereof due to ously referred to. Eflicient cushionin and protection of the article is thus attame -Unfolded sheets, as illustrated in Fig. 4,

may be stacked andnested for shipment in the same manner as described with respect tothe embodiment of Fig. 1.

If desired, the outer surface of walls 26 may be ironed or sized for receivin printing or stamping. Furthermore, in bot embodinfients, the dome-shaped members may be of the same form on each flap, or, being cushion members, they may take other shapes to suit the'particular characteristics of the article to be packed. Likewise, cushioning or spacing members may be bulged from the walls 16, or 26 of the embodiment. The improvements arenotlimited to any particular size but may be embodied invarious sizes to suit the texture prevl- Ill tion in breakage, constitute further advanv I tages of the improvements.

Various other advantages, and modifications of the present improvements within the scope of the invention, ma occur to those skilled in the art. It is un erstood that the improvements are not limited to the embodiments illustrated and described.

2. A collapsible container formed of sheet material and having a body portion and flap portions extending from opposite edges thereof, and dome-shaped mem ers protruding from each fiap portion, one of said flap portions being hinged directly to said body portion and havin its dome-shaped member -protruding inwar ly when the container is olded into article surrounding condition" whereby the surface of said flap portion is flush with the outer end of the container.
